ARM: MXS: power-init: Add parameters to mx28_power_init()
Instead of introducing new functions each time a new power supply situation is to be added, this patch adds parameters to mx28_power_init. Right now there are three parameters: - has_battery - true when this board has a battery. - use_battery_input - true when this board is supplied from the battery input, but has a DC source instead of a real battery - use_5v_input - true when this board can use the 5V input The third one is introduced with this patch and allow to boot a board from 5v (USB) source only. The main necessary change this needs is that the DC-DC converter must always be sourced from DCDC_4P2 (DROPOUT_CTRL field of HW_POWER_DCDC4P2) Signed-off-by: Sascha Hauer <>
